摘　　要：以N-羟甲基丙烯酰胺(N-MA)作为自交联剂,采用预乳化种子乳液聚合法制备了自交联型苯丙乳液。该乳液与淀粉复配制取的表面施胶液对新闻原纸进行表面施胶时,成纸施胶度可达16 s,表面强度达2.04m.s-1,均优于2倍(对苯丙乳液)绝干PVA量所配置的施胶液,且相比成本有较大幅度降低,可以替代PVA作为印刷纸张表面施胶剂。With N-hydroxymethyl acrylamide （N-MA） as a self-cross-linking agent, the self-crosslinking styrene-acrylic emulsion was prepared by pre-seeded emulsion polymerization method. The newsprint paper was treated with the surface sizing agent fixed with starch solution, the sizing value could reach 16 seconds, folding endurance was 2.04m.s^-1 ,they ara all better than those with the surface sizing agent fixed with 2 times （for styrene-acrylic emulsion） dosage （as o. d） of PVA and starch solution,and cost was also reduced,so it can instead of PVA as printing paper surface sizing agent.
